Definitions

  • These carbonaceous compacts have the properties of carbon, that is, various properties such as light weight, high strength, high elastic modulus, conductivity, corrosion resistance, heat resistance, and sliding properties.
  • properties of carbon that is, various properties such as light weight, high strength, high elastic modulus, conductivity, corrosion resistance, heat resistance, and sliding properties.
  • high modulus conventional materials are relatively advantageous when rigidity is required, while on the other hand, There is also a drawback of lacking, and from the standpoint of safety, higher strength is currently required.
  • the above-mentioned elastic graphite particles are used as an aggregate, and the above-mentioned binder is mixed with the aggregate.
  • the amount of the resin is blended so as to be 0.1 to 5 parts by weight, particularly preferably 5 to 5 parts by weight with respect to 1 part by weight of the elastic graphite particles. If the amount of the resin exceeds 5 parts by weight with respect to 1 part by weight of the body particles, it is not preferable because the bulk density of the obtained molded article tends to increase.
  • the compact obtained in this way has properties that are lightweight and excellent in elasticity, which are not present in conventional carbonaceous compacts.
  • the heat resistance, the heat resistance, and the like may be inferior to those of the carbon material because they are affected by the properties of the binder resin.
  • the conductivity, slidability, etc. are sufficiently maintained because a mixture of the elastic graphite particles and the binder resin can be obtained uniformly. Can be held.
  • the yield of aqua meth- es was 133.5% by weight based on the raw coke.
  • the aqua mesoface was placed in a 500 ml cylindrical glass container, and then placed in a salt bath previously heated to 30 ° C. and held for 30 minutes. Then, 40 hours in a stream of argon. The mixture was heated to 280 ° C. at a rate of temperature increase of C / hr, held for 30 minutes, and graphitized.
  • the yields based on the raw coke were 85 and 52% by weight, respectively.
  • the compression elasticity (compression rate, recovery rate) of the graphitized sample was measured as follows.
  • the yield of aqua mesophase was 133% by weight based on the raw coke.
  • Transfer this Aqua Method into a 500 ml cylindrical glass container.
  • the mixture was put into a salt bath heated to 300 ° C. in advance, and kept for 3 minutes. Then, in an argon stream, 400.
  • the mixture was heated to 2800 ° C. at a heating rate of Cr and held for 30 minutes to be graphitized.
